Basic Stoichiometry

Basic Stoichiometry

This webinar covers an important foundational topic for MCAT chemistry: stoichiometry. You will learn how to convert between mass and molar quantities, how to express and calculate concentration, and the applications in dilutions and Beer’s law.

At a glance


Essential skills

  • Convert between mass and mole

  • Recognize and calculate with different measures of concentration

  • Apply Beer's law

  • Calculate dilutions


Knowledge Fundamentals

  • The basic units of stoichiometry

  • The different measures of concentrations

  • The difference between empirical molecular formulas


On the MCAT

  • Stoichiometry is calculation-heavy, and an area where the MCAT test writers know they can waste your time - don't give them the satisfaction

  • Always check the units of your answer, always write your work out, and simplify or cancel out math wherever possible


I think these webinars are really helpful! I like how they’re styled like a TED talk, so they don’t interfere with the day, but they’re really helpful review 🙂

I found everything helpful about these webinars: the explanations, the illustrations, just everything!

Amazing material conveyed concisely and in great detail!

The wealth of information and sample questions are great.

“These 30 minute FREE, live videos conducted each Friday helped me get through the pandemic. Weike is an exceptional tutor, and being able to ask questions after she’s done was magnificent. These webinars have even helped me in class subjects such as Biochemistry.  I’m looking forward to starting one-on-one tutoring with Cambridge Coaching, and I’m already feeling confident about taking the MCAT when the time comes.”
